I can think of two things for the OP to try for improved mileage. Since the 2.7 engine is right at max towing capacity, definitely run in tow haul mode. Assuming it works the same as most other Ford tow haul modes it will at least raise the shift point RPMs keeping the engine from lugging with better fuel mileage. In addition it will be much easier on the transmission (read-> less transmission failure problems). Secondly, the 3.5 Eco-Boost recommends premium gas when towing, so I would guess the 2.7 is the same. That allows the engine to advance the timing for better efficiency. Only a couple of test runs would show if the mileage improved enough to pay for the premium cost.
